DISH AND LINER THEREFOR.

Application filed September 13, 1923. :Serial No. 662,483.

.10 liners therefor, especially to utensils of the character which are in daily and popular use in homes, restaurants, soda fountains and the like, where itis necessary for the same dish to be repeatedly used by different persons, and much labor is required to keep same in a sanitary condition.

I am aware that various and sundry sanitary dish liners have been devised but they,

as a general rule, are objectionable for the reason that no provisions are made in the construction of either the liner or the dish in connection with which it is' to be used for a positive union between thetwo so that the possibility of relative movement therebetween while in use is obviated. The result is that when a container, equipped with the character of liners now in use, is filled with a somewhat viscous substance, the same cannot satisfactorily be removed therefrom with the aid of an. ordinary knife, fork or spoon without such a liner being turned relative to or lifted entirely out of the said containerQ My invention contemplates the production of dishes and'liners therefor which shall be free from the objections above referred to,

and at the same time be more efficient in use, simple in construction and can be man ufactured and sold at a reasonable cost.

More specifically stated the objects of the invention are: p

To construct dishes or containers and liners for same which shall be provided with cooperating matingelements adapted to interlockingly and positively engage each other in such a manner as to produce an almost unitary structure, incapable of accidental separation while in use; i

To construct the container and the liner therefor in such a manner that the interliner that the contents thereof will cooperate to increase theintimacy of contact between the said liner and container.-

I Withthe above and otherobjects in view, whlch will be made more apparent as the description proceeds, the invention will now be more specifically set forth, reference be- 1ng had to the accompanying drawings whlch form a part of this application and in which:

Fig- 8 is a modified form'showing the liner provided with a bead adapted to engage a groove on the outer rim of the container. I 1

Fig. 9 is an outside view ofthe container as shown'in Fig. 8'with the liner removed.

Referring now more specifically to the drawings wherein corresponding numerals are used to designate similar parts in the different views, the container 1 is provided on its outside top edge with a turned-down annular flange 3 and with an annular groove 5 in the interior bottom surface. The opening of the groove 5 is slightly constricted and its bottom and sides are preferably curved. V 7

Within the container is the liner 2 with its outside surface conforming to the configuration of the interior surface of the container. The liner 2 is made of paper or any other light material which can be easily pressed or stamped into the desired form. This liner is preferably stamped from a slngle sheet 110 and in which event the wall will have overlappin corrugations as is well known to strengthen it. At the juncture of the side and bottom wall of the liner, an annular bead 6 is formed and on the top ed e of the liner is formed the overturned annu ar lip 4. The bead 6 is so shaped that it fits snugly, preferably under slight compression, into the groove 5 of the container, and the overturned lip 4 envelopes and clamps over the flange 3 of the container. Both the head 6 and lip 4 are slightly resilient, due to the character of the material used.

When the liner is assembled in the container, as shown in Fig. 2, the entire outside surface of the liner is supported by the entire interior surface of the container. The resiliency of lip t will cause it to frictionally engage the flange 3. Likewise the bead 6 of the liner, being inherently resilient, will, when forced into the constricted groove 5 of the container, expand against the walls of said groove, thereby effecting a most intimate frictional contact therewith. It is to be noted that the intimacy of this contact will be augmented by the pressure exerted thereon by the weight of any substance that may be in the vessel when in use. The peculiar configurations of the bead and groove form a dovetail connection thereby positively interlocking the elements in such a manner as to obviate the possibility of any accidental separation or relative movement therebetween. The bead and groove is shown located at the bottom or top of the liner and container but it is obvious that the same could be formed at any intermediate surface of the walls.

In addition, the frictional andgripping action between flange 3 and lip 4 will be sufficient to positively lock the elements but the liner may be readil removed by the grasping of the lip with t e fingers and pulling it out of the container without any danger of soiling the same.

In most instances the frictional engagement between the liner and container will hold the members assembled and prevent rotation of one relative to the other. But in suchinstances when the liner is applied to lar e mixing dishes, there will be a stronger ten%ency for the liner to turn and twist when the contents of the dish are being rapidly stirred. Continued turnin and twist; ing of the liner will necessari y cause the liner to break and permit the contents to flow into the container.

To adapt my device for such heavy work and at the same time avoid any danger of the liner becoming dislodged from the container when subjected to twisting or tortional forces, I have provided the special construction shown in Figs. 3 and 4.

Fig. 3 shows the side walls of the liner near' the top edge thereof provided with pressed-in portions which form protruding surfaces on the opposite side of same. These protruding surfaces fit into corresponding depressions formed on the side walls of the container. By this arrangement the frictional contact is increased and the possibility of slippage between the liner and its container is obviated. If a more positive locking'together between the elements is required, corrugations such as shown at 8 and 9 (Figs. 4 to 6 inclusive) may be formed, respectively, on the outer rim or bead of the base of the liner and in the groove at the circumference of the bottom of the container. These V-shaped ridges and grooves are, as it is plainly obvious, adapted to interfit one into the other, forming a more positive lock between the elements.

I The above described mterlocking means may be employed either separately or jointly, that is to say, one embodiment may have both, or two separate devices of this character may be equipped with one, whichever is preferable and most .suited to the use to which the vessel is intended to be put.

The contour of the corrugations formed on the base of the liner and onthe bottom of the container, respectively, are so formeu as shown in Fig. 4 that they not only prevent movement of the liner in a circumferential direction but also in an axial or longitudinal direction. It will also be seen that in. this instance, as in the structure shown in Fig. 2, the contents of the vessel will press the opposite walls of the bead on the liner radially outward and inward, respectively, into the undercut concavities of the opposite side walls of the groove in the container, thereby augmenting the resistance of th liner to a pull in an axial or longitudinal direction.

The embodiment of the invention illustrated in Fig. 7 shows the wall and bottom of the liner formed in two parts 10 and 11. They are so joined that their beaded edges 12 and 13 overlap each other and fit into the groove 5 of the container. The overlapped beaded edges are resilient and expand to make a tight joint as well as to friction-ally engage the container within the groove.

Another embodiment of the invention is shown in Figs. 8 and 9. In this Instance the outer surface'of the rim of the dish or container is provided with a circumferential i is too obvious to require special description;

It is further to be noted that the overhanging clinching lip of the container ter-' minates in a stiff annular rib 1 8. This con-- struction gives stability to the device and renders it capable of more firmly gripping the rim of the container and also preventing the collapsing of the same when it is being removed after use. I

\Vhile I have shown my invention as be ing applied to dishes of a rather large size It is to be understood that this disclosure and description are merely for the purpose of illustration, and the same combination oi parts and arrangement of elements may be applied to plates, cups and dishes of any size or descriptlon. It is thus obvious that the invention herein above set forth may also be exemplified in numerous other alternative constructions and I accordingly reserve the right. of adopting all such legitimate constructions as may fairly be embodied within the spirit and scope of the invention as set forth in the annexed claims, and do not timit myself to the precise details of construction and arrangement shown.

Having thus describedmy invention, what I claim and desire to secure by Letters vPat- .ent is:

1. In combination with a containel, a liner having a bead stamped on its bottom surface,

and a resilient overhanging lip on its upper edge, said head engaging a groove 1n the bottom of the container, and said lip engaging the groove in the bottom Ian annularfiange on the top edge of the container. A 1.

' 2. The combination of a container and a linerthe'reion-a corrugated resilient means attachedfto-the liner and engaging a similar- 1y corrugated grooveiin the container.

3. The combination of a co'ntainer and a liner, a beadformed near the ed e of the liner bottom and over-lapping anot er annular bead formed near the edge of the linei wall, both beads being frictionally held 111 a I groove in the container.

4. In combination witha container, a liner therefor, a hollow resilient head on the liner and a groove in the container, the liner being held in contact with the entire inner surface of the container solely by means of the said bead and groove.

. 5. In combination with a container, a liner therefor, top and bottom beads on the liner, an outwardly flaring rim at the top edge and an undercut groove at the bottom of the oontainer,"-the top bead of the-liner adapted to over-lap and clinch the said outwardly flaring rim of the container, and the bottomhead of the liner adapted to be inserted in V of the container, the respective bead and rim, bead and groove engagements constituting the sole holding means between the said liner and container.

- In witness whereof I have hereunto set my hand and signed my name to the foregoing specification. w
